ã€business background】
Campus intelligence is the use of information means and tools to digitize campus resources, management and service processes to form a campus digital environment, so that the real campus environment can be extended in time and space with the information system. The purpose of the digital campus is to plan and implement the construction of campus informatization with a hierarchical and holistic view, to better organize and classify the information on the campus, let teachers and students quickly find the information they need, and provide an online information exchange environment for teachers and students At the same time, it also allows managers to manage their data in a scientific and standardized manner, and publish this information quickly and accurately to serve teachers and students.
The intelligent weak current system is the most basic and most important component of an intelligent campus. Its essence is to innovate the traditional campus environment. Through information technology, a digital environment integrating teaching, scientific research, management and life in colleges and universities is built. Meet the individual needs of teachers for scientific research, teaching, management and students for learning, scientific research, and life. In such a new digital environment, teachers can improve the academic and scientific research level and cultivate excellent students through a good scientific research environment, training environment and teaching environment; students can improve through a good learning environment, training environment and living environment. To develop your own potential with your own comprehensive quality.
ã€design concept】
In the construction of intelligent systems on campus, network technology, computer technology, communication technology, control technology, and multimedia technology are the main technologies used in each system.
We consider the design of each system according to the following levels:
â– Physical platform layer-including various types of computer rooms and floors, weak electricity rooms and weak electricity comprehensive pipe network. The area planning of the main machine room, pool machine room and building weak current room of each system shall be considered in accordance with the layout requirements of each weak current system equipment, and sufficient space shall be reserved for maintenance and equipment increase. The weak current pipe network is further subdivided into indoor bridges and pipes, and outdoor pipe network systems. It is necessary to comprehensively consider and balance the pipe bridges of each wiring system.
■Wiring link layer—including special wiring systems and connection adapters for each system, structured integrated wiring system, IDF rack and cabinet. In addition, from the perspective of cost savings and ease of installation and maintenance, it is recommended that each special system should adopt standardized copper cables and optical fiber wiring as far as possible in technical selection, so as to uniformly consider cable selection and construction in the structured integrated wiring system.
■Transmission equipment layer—It is the basic platform for the internal communication transmission and exchange of each weak current system, including the transmission equipment and computer network system of the special system. From the perspective of cost savings and ease of integration, installation, and maintenance, it is recommended that each special system consider TCP / IP protocol mode as far as possible in terms of technical selection to facilitate future expansion. Considering that there are frequent virus outbreaks on the campus network, which affects the network transmission speed, and there is also the possibility of hacker attacks, it is recommended to supervise an independent intelligent private network to provide private network transmission channels for BA, One Card and other systems.
■Support platform layer—It is the center of information processing, storage and management, and provides a hardware operating platform for the upper layer software, including support equipment for special systems and IDC center. From the perspective of school management and maintenance, build an IDC center to unify the management of the school's systems and departments' servers, and use the good computer room environment and power supply measures and strong technical service to manage the servers of each system.
■Application software layer—It is the highest layer of 5 layers, directly facing customers and application requirements. Has the most personalized design requirements. Software secondary development and system integration are the key points considered at this layer. Therefore, according to the above characteristics, we subdivide it into three sub-layers: standard software products, customized software products, and system integration software products. The next sub-layer needs to provide a good software protocol interface to the previous sub-layer to ensure the smooth implementation of the entire weak current intelligent system integration in the future. Including the internal integration of each subsystem and the total integration of IBMS to BA, FA, PA, One Card and other systems.
